    摘要: A method and system to recognize input events from a plurality of input devices. Each input device is coupled to a device driver or similar device specific code and a recognition provider. Upon attachment to the system, the recognition provider registers the known input events which the input device is capable of transmitting at the recognition subsystem. The recognition subsystem sends an identifier back to the recognition provider for each registered input event. When the recognition provider receives one or more input signals from the input device which are recognized as an input event, the provider sends the identifier to the recognition subsystem. The input event is transmitted to a process running on the system which may interpret the input event or request translation by the recognition subsystem. The invention is useful to introduce new input devices to a system without requiring modification of the existing processes.

    摘要: A system is disclosed for managing a plurality of interrupt handlers in a linked-list data structure, for servicing a plurality of input/output devices sharing a common interrupt line in a microcomputer. The system provides for an orderly method to link a newly loaded interrupt handler routine into a linked-list data structure consisting of previously loaded interrupt handler routines. The system further provides for an orderly method to share a common interrupt line among a plurality of input/output devices being serviced by the interrupt handlers. The system further provides for an orderly means to unlink a particular interrupt handler routine from the linked-list data structure when a corresponding input/output device is to be deactivated. The system finds special utility in a multitasking operating system environment where input/output devices can be deactivated in a different sequence from that in which they were originally activated.

    摘要: Improvements in the art of sensor and display technology now make the implementation of a workpad concept feasible. While prior art touch displays are acceptable for short, casual use tasks, they may not be feasible or suited for intensive use tasks. Recent improvements in the optical qualities (brightness, contrast, viewing cone) of flat panel displays, such as LCDs, allow implementing a touch screen for use in a horizontal orientation. This greatly improves the human factors for applications involving extensive pointing, drawing, or writing.

    摘要: A computer system enables a user to design touch activated keyboards for use on a display surface without writing code. The computer system enables the user to resize and move the keyboard image anywhere on the display to allow the concurrent display of other applications running in an integrated operating environment. Computer system actions can be assigned by the user to each key. An execution unit displays the selected keyboard, determines whether a key has been touched and executes the appropriate action for each key touch.
